# imgproxy vs alternatives benchmark

## Setup

- c5.xlarge AWS instance: 4 CPUs, 8 GB RAM
- Ubuntu 18.04
- Go 1.12
- Python 2.7
- Vips 8.7.4

All the tools were launched with their default settings except the following (where applicable):

- Concurrency was set to 8;
- Filesystem image source was configured. Where not applicable, local nginx was used as the image source.

## Benchmarking

We used [Apache HTTP server benchmarking tool](https://httpd.apache.org/docs/2.4/programs/ab.html) (a.k.a `ab`):

```bash
ab -n 1000 -c 4 $url
```

The source image is a [photo of Wat Arun](https://upload.wikimedia.org/wikipedia/commons/b/b7/The_sculptures_of_two_mythical_giant_demons%2C_Thotsakan_and_Sahatsadecha%2C_guarding_the_eastern_gate_of_the_main_chapel_of_Wat_Arun%2C_Bangkok.jpg) (JPEG, 7360x4912, 29MB).

The tools were requested to resize it to fit 500x500.

## Tested tools

- [imgproxy](https://github.com/imgproxy/imgproxy) itself, v2.2.13

URL: `/unsigned/rs:fit:500:0/plain/local:///wat-arun.jpg`

URL: `/fit?width=500&height=500&file=wat-arun.jpg`

- [Pilbox](https://github.com/agschwender/pilbox), v1.3.4

URL: `/?url=http%3A%2F%2Fimages.dev.com%2Fwat-arun.jpg&w=500&h=500&mode=clip`

- [picfit](https://github.com/thoas/picfit), master branch ([fff7d2e](https://github.com/thoas/picfit/tree/fff7d2e83d23b1c716fed484bb5d0775a49c9a71))

URL: `/display/resize/500x0/wat-arun.jpg`

- [imageproxy](https://github.com/willnorris/imageproxy), master branch ([d4246a0](https://github.com/willnorris/imageproxy/tree/d4246a08fdec341ddf01b09e74e56ee03f9929d0))

imgproxy also uses native Go's `net/http` routing for the best HTTP networking support.

You can see benchmarking results and comparison with some well-known alternatives in our [benchmark report](./BENCHMARK.md).

#### Security

Massive processing of remote images is a potentially dangerous thing, security-wise. There are many attack vectors, so it is a good idea to consider attack prevention measures first. Here is how imgproxy can help:
